It's a race course, not sure what to tell ya. Interesting for motor sport fans, there is the old banking and lots of different events on weekends, like drifting and gymkhana. Also bike races, but we can just pretend that never happened.

The atmosphere during a race is great, however there aren’t many activities around the track other than a run down go carting experience. I recommend Suzuka circuit for people interested in visiting a race track. They have many attractions and you can even go cart around the track.

Best track I have been to in Japan! Lots of events hosted here and you can get access via train/expressway bus and then either taxi (about ¥3,500 one way) or shuttle bus (during certain events, but only run certain times).
